This invention relates to grinding or masticating hogsutilizing a double disk or V shaped grinding wheel cooperating with a pair of fixed anvil knives so arranged as to to the faces of the rotating disk, and has for its object to provide ,a' yielding anvil knife dooror carrier held by breakable 'members, wherebythe carrier may swing back from the rotating disk a predetermined distance to of metal or relatively hard foreign material topass through the machine. In other words the invention has for its object to provide a simple and eflicient safety device forvthe protectionof the hog or mastiundue resistance between the rotary and fixed knives should be encountered.

With the construction'of the invention, the anvil knife door or carrier may yield or swing away from the rotating disk sufiiciently far to permita piece ofm'aterial of maximum size, such a'sfor example 12" x 12 x to pass through the machine without injury thereto orto the driving mechanism thereof.

Another object of the invention is to pro 25 vide strong, durable, eflicient'and inexpensive protection means of the type outlinedwhere bythe' use of friction clutches or the like for t he protection of themachine are entirely obviated; and? in order that it maybe fully .3 understood,;reference is to be had to the ac companyingdrawings, inwhichz Figure lis a s1d'e elevat on of hog-em bodying the 1nvent1on.

The; shaft 2' is driven in the directionof thearrow, Figure 3, and

'0 carriesa disk f V-shape in cross section driven by a pulley 3, or by any equipped with a plurality of cutter knives 5 if; adjustable toward andfrom the faces of the V disk to regulate the coarseness of the out. To

centralize the rotating disk, a pair of adjust-j ing bolts 6are carried by the side frames with their ends in positionto contact with the edges of the disk so that the'shaft and disk may be adjusted: or centerefdbetween the frames.

Vertically above the cutting disk, the frame and casing are SO formedas to provideafilling chute or opening 7 The frame'l to one side of the shaft 2 in the direction of rotation of said shaft, is extended upwardly, V and ournaled in bearings-8 carried by the upper end thereof is a yielding anvil knife shaft-9..

the shaft 9projects beyond the framesl, and";

keyed to the ends of saidshafts are a pair of downwardly. andontwardly inclined arms 12 in abutment with outwardly; proj ecting stop lugs or studs 13 cast or otherwise securedto the, frames 1. .To maintainlthe arms 1 12 against the-stnds'lii' so thatthe' knives shall be properly spaced and to permit the whole assembly to swingto thedottedline. position shown in Figure 1 should strain abovea predetermined maximu'm be placed on the, ma-

chine, the ends of the arms are'held in clamped positio'nfagainst the studs by breakable plates 14L bolted or otherwise replaceably secured to.

the :framesl, as: illustrated. The plates, 14: r

are adapted to Withstand a predetermined strain byybeing formed with a 1 transverse groove or "kerftforming a: breaking point or 1 line i It will be evident from the' above descript-ion' that the strength of the'break-plates "V-shape' .intermeshing with said; rotating frames .1, but'it will be evident that if desired the pivoted carrier may .be formed integrally with a suitable housing or protecting plate so that the entire assembly and housing may swing away from themachine upon the breaking of the safety plates, as will be readily understood. The lower corners of the plates 16 are recessed as at 17 to accommodate the break-plates 14 which preferably should fit flatwise against the frames 1, as shown. It will also be evident that if desired, springs or other shook absorbing devices may be applied to-the arms 12 to prevent the knife carrier 10 from swingingout with such force as to fractureor injure the cover plate 16 of the'mechanism. I

c From the above des'criptiomit will be apparent that I have produced a machine of the character described which possesses all of the features of advantage set forth as desirable,

. and 'while I have described and claimed the preferred embodiment, it is to be understood that Ireserve the right to makel all changes properly falling within the spirit and scope of the appended claims. 1 I claim: 1; In a masticating or grinding'hog, a ro-- tati-ng V-sha'ped cutter, a second cutter of V shape intermeshing with said rotating out; ter,a shaft carrying said second cutter, and

" means 'co-operating with saidshaft to pre- 7 .vent movement of the second cutter away I V I from the rotating cutter.

2. In a masticating or grinding hog, aro-' tating V-shaped "cutter, a secondcutterof V-sha'pe intermeshing with said; rotating cutter, a shaft carrying said second cutter," I ".50

5. In a masticating or grindinghog, a suitable frame, a rotating V-shaped Cutter therein, a shaft journaled on and. extending transversely of said frame, a second cutter of V-, s ape ca ri d bysaid shaft a d. i termes ing with the otating cutter, arms secured to said shaft, and breakable lllgsi n-contact with said arms to prevent movement'of the second cutter awayfrom said first cutter.

6. In a masticating or grinding hog, a suitable frame, a rotating V-shaped cutter therein, a shaft journaled on and extending transversely of said frame, asecond cutter of V- shape carried by said shaft and intermesh ing with the rotating cutter, means for pre-" venting the second cutter from moving in one. direction, and breakable lugs to prevent movement of the'secondcutter in the oppo site direction. 7 g

'7. In a masticating or grinding hog, a suit.- able frame, a rotating cutter therein, a shaft journaled on and extending transversely .of the frame, a second cutter carried bysaid, shaft for cooperating with the rotatingcut ter, arms carried by said shaft, stop lugs on the frame for contacting with said arms for preventing movement of the second cutter in one direction, and breakable plates coopera ating with the arms in preventing movement of said cutter in the opposite direction.
